Former Ajax star Peter Boeve has hailed the form of Southampton defender Virgil van Dijk.
Boeve rated Van Dijk as Holland's best in their World Cup qualifying defeat to France this week.
"He won lots of duel, in the air and also on the ground. He controlled the defence.
"With how the Oranje now play, with little space at the back, he is the best option," said Boeve.
"The system suits him well."
